Satan is the Lord of Pandaemonium. His lieutenants include Beelzebub and Astaroth (who is referred to as a male fallen angel, unlike his GBA and PSP appearance). Emperor Mateus strikes a deal with him to summon hellish creatures into the mortal realm.

In the past, Satan's main power came through influencing others, with the conduit of influence being that of a person's natural level of malice. Palamecia proved to be an easy target for him to spread his influence into the kingdom, and if a ruler were to be immune to Satan's influence, he would find a way to eliminate them. Such a fate befalls that of the Emperor's father, wanting to open the Palamecian borders for diplomatic relations with other kingdoms. Satan was unable to dissuade the monarch, and so gives him a heart-attack, killing him instantly. As soon as Mateus is crowned Emperor, Satan has him as a pawn in his game, knowing that Aile, the Emperor's mother may be onto his plot. Satan removes Mateus' memories of her, as influencing him to outright kill her wasn't an option.

When the Emperor is defeated by Firion and his friends, they find the Stone of Iludia containing Satan's soul and destroy it sending Satan back to hell to where he (presumably, considering the novel doesn't mention the Emperor's return) takes the form of The Emperor of Hell and attempts to take over the world a second time, this time in person, while Mateus's soul enters Arubboth and becomes The Emperor of Arubboth.

[view·edit·purge]Satan comes from a Hebrew ha-Satan which means "the accuser." It is the name of the Devil in Abrahamic religions. Satan is also one of the seven princes of Hell in Christian Demonology. He is attributed the deadly sin of Wrath.

[view·edit·purge]A demon is "an evil spirit or devil, especially one thought to possess a person or act as a tormentor in hell."
